Oled lighting device

Abstract

An organic light-emitting diode (OLED) lighting device comprises an organic light emitting unit and a power supply unit. The organic light emitting unit has a substrate, and a first electrode layer, an organic light emitting layer and a second electrode layer sequentially laminated on the substrate. The first electrode layer and the second electrode layer have a first contact portion and a second contact portion extending toward the periphery of the substrate, respectively. The power supply unit has a plurality of power supply elements. Each power supply element has a conductive terminal portion and an insulating portion. Each conductive terminal portion has an inner surface and an outer surface opposite to the inner surface. The inner surfaces are correspondingly connected to and completely cover the first contact portion and the second contact portion, respectively. Each insulating portion completely covers the outer surface of each conductive terminal portion.
